Proposed rule · 2026-13403

Air Plan Approval; Alabama; Transportation Conformity

The Environmental Protection Agency (EPA) is proposing to approve a State Implementation Plan (SIP) revision submitted by the State of Alabama, through the Alabama Department of Environmental Management (ADEM) on April 7, 2026. The SIP revision replaces the previously approved transportation conformity memorandum of agreement (MOA) with an updated MOA concerning transportation conformity criteria and procedures related to interagency consultation, conflict resolution, public participation, and enforceability of certain transportation-related control and mitigation measures. The SIP revision also makes a minor stylistic change to the Transportation Conformity and General Conformity rules in the Alabama SIP. EPA is proposing to determine that Alabama's April 7, 2026, SIP revision is consistent with the applicable provisions of the Clean Air Act (CAA or Act).
